Amperometric biosensors based on the use of glucose oxidase (GOx) are able to combine robustness electrochemical techniques with specificity biological recognition processes. However, very little information can be found in literature about fundamental analytical parameters these sensors. In this work, behavior an amperometric biosensor immobilization GOx using a hydrogel (Chitosan) onto highly ordered titanium dioxide nanotube arrays (TiO₂NTAs) has been evaluated. The GOx-Chitosan/TiO₂NTAs...
Preventing relapse after resection of a primary tumor continues to be an unmet clinical need. Development adjuvant biomaterials with the capacity kill residual cancer cells is importance. Here we developed library metallo-alginate hydrogels containing high concentrations metallic ions such as Ca2+ in combination Zn2+, Li+, or Mg2+ disrupt homeostasis mitochondria by local hyperthermia. To synergistically and suppress growth rechallenged tumors, embedded oncogene-silencing nucleic acids (mTOR...
Hydroxyalkanoyloxyalkanoates (HAA) are lipidic surfactants with a number of potential applications, but more remarkably, they the biosynthetic precursors rhamnolipids (RL), which preferred biosurfactants thanks to their excellent physicochemical properties, biological activities, and environmental biodegradability. Because natural highest producer RLs is pathogenic bacterium Pseudomonas aeruginosa, important efforts have been dedicated transfer production heterologous non-pathogenic...
Bioanalytical methods, in particular electrochemical biosensors, are increasingly used different industrial sectors due to their simplicity, low cost, and fast response. However, be able reliably use this type of device, it is necessary undertake in-depth evaluation fundamental analytical parameters. In work, parameters an amperometric biosensor based on covalent immobilization glucose oxidase (GOx) were evaluated. GOx was immobilized using plasma-grafted pentafluorophenyl methacrylate...
In the context of ever-growing interest in cyclic diaryliodonium salts, this work presents synthetic design principles for a new family structures with two hypervalent halogens ring. The smallest bis-phenylene derivative, [(C6H4)2I2]2+, was prepared through oxidative dimerization precursor bearing ortho-disposed iodine and trifluoroborate groups. We also report, first time, formation cycles containing different halogen atoms. These present phenylenes linked by hetero-(I/Br) or -(I/Cl) pairs....

Leland C. Clark Jr. and Champ Lyons introduced in 1962 the principle of first electrochemical biosensor with immobilized glucose oxidase (GOx) [1]. This device was specifically designed used for fast analysis blood samples from diabetics. Since then, field has experienced important growth. In last few decades, this been widely explored many different environments, such as clinical, biotechnological, food pharmaceutical. type is object attention because it allows high specificity,...
